On Saturday, Mitt Romney announced that Rep. Paul Ryan from Wisconsin would join him on the Republican ticket in November.
Ryan gained traction in the party with his budget plan, which was touted as the prime example of a conservative economic plan. Even President Obama granted that Ryan is an intellectual force in the GOP.
And while Democrats might not see Ryan as much of a threat, some Republicans think he's more than his ill-favored budget plan.
